Dimorphina nodosaria d'Orbigny. (PI. V, figs. 18-22.) 



Dimorphina nodosaria d'Orbigny, 1846, Foram. Fobs. Vienne, p. 221, 

 pi. xii, figs. 21, 22. 



The tests are in excellent condition, some of them quite trans- 

 pirent; but even in these latter ones I am not able to indicate in 

 the drawings all the chambers of the polymorpliine commencement. 

 The specimens are curved and round in section, and all are in the 

 microspheric condition. I am of opinion that they are closely 

 related to, if not identical with, those I have described (and figured) 

 under Nodosaria radicula, dentaline form. I have excellent 

 examples of both forms from Darvel Bay, lat. 4° 11" N., long. 

 118° 37" E., 315 fms. Some of the specimens of the two forms are 

 practically identical apart from the polymorphine commencement.

I liave brought four specimens under this heading, three of 

 which, however, have a tendency towards U. pygmgex. 



TJvigerina asperula Czjzek. 



TJvigerina asperula Czjzek, 1848, Haidinger's Naturwiss. Abhandl., vol. ii,.

Capital examples occur. Some of them are more drawn out 

 than the "Challenger" specimens, and all have the earlier chambers- 

 more comT)act.
